Justin, as I did, check whether you have a Purolator or Telcomite filter
housing. Buy a new spring ( and the tiny ball, as long as you are in there)
from TRF or one of the others. Replace it -1/2 hour job - then set it up
according to the manual. I.e. - With the engine at operating temp. gradually
rev to 2000rpm. The pressure should steadily rise to 75psi.. At 2000rpm the
pressure should drop to 70. If that does not happen then loosen the nut and
adjust the screw CW to increase the opening pressure and CCW to decrease it.
"Piece of cake" and it will then work properly. Cheers.
